=head1 DESCRIPTION
|
|
|
|
|
|
|
|
|
|
The SM4 blockcipher (GB/T 32907-2016) for EVP.
|
|
|
|
|
|
|
|
|
|
All modes below use a key length of 128 bits and acts on blocks of 128 bits.

=head1 RETURN VALUES
|
|
|
|
|
|
|
|
|
|
These functions return a B<EVP_CIPHER> structure that contains the
|
|
|
|
|
implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for
|
|
|
|
|
details of the B<EVP_CIPHER> structure.
